A matrix-bridge written in Go to let you read and write your emails in matrix. You can have multiple emailaccounts in different private rooms and write emails to one or multiple recipients.

Matrix room: #jojiiMail:matrix.jojii.de

This bridge is currently in development. Its not 100% tested
You can run the install.sh to install it. If that doesn't work, use the steps below and contact me so I can fix it.

Clone this repository and run inside the folder

go get    #fetch the required dependencies

and

go build -o emailbridge    #compile it

Afterwards execute the created binary(./emailbridge).

--> Configure

DockerHub: https://hub.docker.com/repository/docker/jojii/matrix_email_bridge

Run

docker pull jojii/matrix_email_bridge

to pull the image. Then create a container by running

docker run -d \
--restart unless-stopped \
-v `pwd`/data:/app/data \
--name email_bridge \
jojii/matrix_email_bridge

After configuring the bridge you have to run

docker start email_bridge  #start the bridge

Note: 'localhost' as 'matrixserver' (in cfg.json) wouldn't work because of dockers own network. You have to specify the internal IP address of the matrix-synapse server!

You have to adjust the config file (cfg.json) to make it work with your matrix server. Invite your bridge into a private room, it will join automatically.
If everything is set up correctly, you can bridge the room by typing !login. Then you just have to follow the instructions. The command !help shows a list with available commands.
Creating a new private room with the bot/bridge lets you add a different email account.
Using following command allows you to get an accesstoken for a given user:

curl -X POST -H "Content-Type:application/json" http://<domain>:8008/_matrix/client/r0/login -d '{"type":"m.login.password","identifier":{"type":"m.id.user","user":"<USERNAME>"},"password":"<PASSWORD>"}'

Note: you should change the permissions of the cfg.json and data.db to 640 or 660 because they contain sensitive data, not every user should be able to read them!
